IMPROVEMENT IN CAR-AXLES;

Tithe Stlge lmle ftitttth In in this gratin min amt making part of thesame.

TO ALL WHOM IT MAY CON CE'RNz- Be it known that I, WILLIAM B.FAHN-ESTOCK, of the city of Lancaster, in the' county of Lancaster, andState of Pennsylvania, have invented an Improve-d Independent Gar-Wheeland Axle; and I do hereby declare that the following is a full and exactdescription thereof, reference bein had to the accompanying drawiugs andto the letters of reference marked thereon. I i

The nature of my invention consists in placing the wheels of a car onseparate and independent axles, so that, in passing round a curve, thetwist and strain on-th'e axle at present in use are avoided;

To enable others skilled in the art to make and use my invention, I willproceed todescriheits construction and operation.

additional-bearings between the wheels, and. in the truck so constructedI place the wheelsA A, Figure 1, which, lilre Figure 2, is a frojnt viewof the wheels and axles. g

. I construct my axles either with a bearing in the centreyat a c, fig.1, (being. in two pieces, and the ends being placed in contact with eachother,) or with an intervening adjustable or stationary'piecqD, placedbetween the ends of said axles, the object, in either case, being toprevent the wheels from coming together.

When I use an intervening piece between the ends of the axles, I arrangeon thetruck two inside bearings for the axles to rest in, at c a, c o,and when the'picce D is not used, I employ only one,'-as at c c, fig l.

The piece D is so made that the ends 6 b are kept against the pivotedendsiof the axlesby means of the arms a a and screw r From thisdescription of my invention it will be seen that'the wheels and axles,when placed intheir position on the truck, act entirely independent ofeach other, and yet cannot be forced nearer each other than if keyed ona single axle. i

I am aware that car-axles in two pieces, united by'a cylinuric coupling,are not new I therefore make no claim to..thisldevice', but

'What I do claim as my invention, and wish to secureby Letters Patent,isg 'The plate D, constructed and operating as described, in combinationwith a divided-axle, asspecified, and

for the'purpose set forth.
